Unable to attack after leaving and entering the server.
and I don't know if it's a bug or intended, but after death, the skills you learn are lost.

You can prevent the removal of skills when you die by /gamerule keepSkills true.
By the way, can you attach a video or screenshot of the bug you mentioned?
